We present an experimental study on two key elements to design a low phase noise coupled optoelectronic oscillator (COEO). Fiber lengths and dispersions are investigated to highlight the differences between the optical and optoelectronic loops. After optimization, a 10 GHz COEO at 1.5 μm with a total of 590 m of fiber exhibits phase noise levels of −125 dBc/Hz at 1 kHz and −140 dBc/Hz at 10 kHz.
We present our recent results on a 10 GHz coupled optoelectronic oscillator (COEO). With a total of 550 m of fiber, the COEO exhibits phase noise level of −140 dBc/Hz at 10 kHz and −137 dBc/Hz for the first spur.
We present a direct measurement of the intracavity dispersion of a coupled optoelectronic oscillator (COEO). The measurement can be performed while the COEO is oscillating, taking into account the dispersion of the modulator and the saturated active medium, without any other component than the ones composing the oscillator. It eases the dispersion management before the detection stage for minimal...
We present a 10 GHz dual loop optoelectronic oscillator (OEO), with very low phase noise (−144.7 dBc/Hz at 10 kHz) and low spur level (−145 dBc/Hz), despite using short fibers (1 km/100 m). The OEO is designed thanks to a simple model, which shows good agreement both with single and dual loop configurations.
